- Compact, lightweight, sharp, excellent detail, tenacious, accurate and quiet AF. Gives an honest 1:1. Not a very trivial angle for macro - before that, the Canon had the widest 50 / 2.5 compact macro. Cool))) - with diodes))) The workmanship is very good.
- For me, the lens had two real shortcomings, one of them is stupid, the other is inconvenient. The first one is stupid - the lack of an AF limiter, for some reason, Canon does not consider it necessary on crop glasses. The subject's AF is accurate and tenacious, but in the case of a complex bright background, no, no, and it will try to cling to it. The second - inconvenient - the lack of a normal manual. Those. hand focus - only electronic, it's sometimes really inconvenient, it's easier to turn everything off in figs and focus with a box. Why it was impossible to make a normal manual in macroglass, I do not understand. Well, if there was a slightly larger lens, so what? The rest is quite. And, well, there’s no protection yet, the disadvantage is number 2,5, but it’s only on lyalki for canon, it’s not supposed to be cropped glass at all.
